Bring Jack back and do the PTSD properly. No insta cure and make Jenn supportive. Then have Jack and Jenn work together as either reporters or private investigators. Put more time into characters such as Abigail and Brady and Lucas and less Sami and E.J. I actually like E.J. but it's total overkill at the moment. If PR has gone then make Hope a strong independent woman. She would be a great matriarch for the Horton clan.
